Solution Overview
Problem
Existing collapsible outdoor structures, such as sunshades and tents, face challenges with stability, versatility, and ease of setup and teardown, particularly requiring multiple people and being cumbersome for single-person use, especially on hard surfaces.
Innovation Solution
A collapsible structure featuring two standing frames with extendable linkages, allowing for easy folding and unfolding, and a sliding mechanism that enables self-standing stability without ground fixation, using pivot points and telescoping poles for adaptability and portability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If traditional tarp structures are used with multiple supporting poles and ground stakes, then stability is improved, but ease of operation deteriorates as it requires multiple people and takes up space
Solution Approach 1:
The structure is divided into modular components: telescopic poles with multiple sections, interconnected linkages, and integrated cross-braces. Each pole can be independently adjusted and the structure can be assembled from separate modules, enabling single-person deployment while maintaining stability through the coordinated arrangement of these segmented elements.
Solution Approach 2:
The structure employs dynamic telescopic poles that can extend and retract, and linkages that can pivot and adjust. This dynamic capability allows the structure to transition between compact storage configuration and deployed stable configuration, with the ability to adapt to different ground conditions and user needs without requiring multiple people for manual positioning.
2Ease of operation
If telescopic poles with sliding members are used, then ease of operation is improved for single-person use, but device complexity increases
Solution Approach 1:
Multiple functions are merged into single components: the telescopic pole combines support, adjustment, and connection functions; the sliding member integrates locking and positioning capabilities; the linkage system combines articulation and structural support. This merging reduces the number of separate parts needed while maintaining operational simplicity.
Solution Approach 2:
The telescopic poles and linkages serve multiple purposes: they provide structural support, enable height adjustment, facilitate easy assembly and disassembly, and adapt to various ground conditions. This multi-functionality reduces the need for specialized components for each function, simplifying the overall structure despite the advanced capabilities.
3Adaptability or versatility
If extendable linkages are used to connect standing frames, then adaptability to various surfaces is improved, but device complexity increases
Solution Approach 1:
The structure is designed with pre-configured telescopic sections and articulated linkages that are prepared in advance for various deployment scenarios. The poles come with pre-marked extension positions and the linkages have predetermined pivot points, allowing rapid adaptation to different ground surfaces without requiring complex on-site calculations or adjustments.
Solution Approach 2:
The structure utilizes adjustable parameters including telescopic pole lengths, linkage angles, and cross-brace configurations that can be modified to suit different ground conditions. These parameter changes are achieved through simple mechanical adjustments rather than complex mechanisms, maintaining versatility while controlling complexity.
